What is the registry number of the USS Enterprise?

The registry number of the original USS Enterprise is NCC-1701. This designation identifies the Constitution-class starship commanded by Christopher Pike and later by James T. Kirk in Star Trek: The Original Series.

Within the fictional Starfleet system, “NCC” marks the vessel as a commissioned Federation starship, while “1701” distinguishes this Enterprise from other ships. The Enterprise was commissioned in 2245 and became one of Star Trek’s most recognizable spacecraft through television episodes, animated adventures, and feature films.

The same ship appears in the original live-action series and Star Trek: The Animated Series. It later undergoes a major refit before the events of Star Trek: The Motion Picture, but its registry remains NCC-1701. That continuity is why the original ship should not be confused with later vessels bearing letter suffixes.

The most common mix-up is NCC-1701-A, which identifies a replacement Enterprise introduced after the original vessel’s destruction. NCC-1701-D belongs to the Galaxy-class Enterprise commanded by Jean-Luc Picard, while NX-01 identifies the much earlier Enterprise commanded by Jonathan Archer.
